We will be measuring our brain waves using an EEG.  Please read the following studies published in Nature in preparation for lab next week: Nature Papers

In addition, please bring earbuds/headphones to lab and compile a list of songs (3 familiar and 3 unfamiliar).

EEG Lab Protocol

We will explore the contractile properties of skeletal muscle in the next two labs. For Lab 8, you will follow the protocol and experiments listed below (Parts 1-6) and submit a group lab, and for Lab 9 you will do an independent experiment and writeup.  

Be thinking about what you might explore further and come up with a good testable hypothesis for your independent lab.  Get your independent hypothesis approved by your TA before you leave lab this week (see manual for more details).

Lab 7-8 Toad Muscle Protocol

Here are some resources:

• Thigh and Shank muscles of the frog
• Ventral musculature (superficial)
• Dorsal musculature (superficial)
• Thigh and Shank muscles (another one)

First live animal experiment, this one will be really cool.

Please look over the dissection guide in addition to the lab manual below. You must wear closed-toed shoes to participate.

This will be an individual worksheet assignment. Remember you may work together with your group members to generate figures, but the written portions must be your own.

Toad Heart Worksheet

Heart-Anatomy

Please do the prelab in your notebook and do the prelab quiz on Laulima before class. This is an Individual Worksheet (IWS) lab, due next week.

This is a fun lab, where you will be able to collect an ECG on yourself — a print out of the electrical signals of your heart!

This week we will be looking at ECGs to further our understanding of the Cardiac Cycle. Think about how the heart works, breaking down what is happening at each component of the cycle. Please note the different types of parameters that are informative – pressure, electrical activity, volume, heart sounds, etc. and what they tell us.

Have fun and think about what kinds of hypotheses you can come up with to explain how your heart responds to exercise. Make sure you focus on physiological mechanisms (be specific!) and function. WHY are these things occurring?

Please watch this podcast and read through the lab manual posted below in preparation for lab this week:

In addition, we are providing some tables to help you with data collection this week:

We may be using the Vernier system. If so you can download the Vernier Graphical Analysis software to collect/visualize your data
